Agree with others, they're not too terribly different in style. If I had to, I would call one list 'posh' and the other 'relatively modern staples'.
I would say Frederick and Florence/Beatrice from his list and William and Isabel/Eleanor from your list cross the (fairly small) boundary the best.
Other names to combine the two styles:
Alexander, Benjamin, Charles, Daniel, Edward, George, Joseph, James, John, Nicholas, Nathaniel, Oscar, Patrick, Zachariah
Annabelle, Abigail, Alexandra, Charlotte, Cassandra, Emily, Francesca, Felicity, Georgina, Hannah, Harriet, Joanna, Katherine, Lydia, Madeleine, Matilda, Natalia, Olivia, Philippa, Rebecca, Rhiannon, Susannah, Thea, Victoria, Zara
